说到?br />
<set-property property="cancellable" value="true"/>
可以解决Q马上复制去试下Q行喔，^_^?br />
---------------------------------引用--------------------------------------
Any existing applications that use the Cancel processing will need to modify their struts-config.xml to set the cancellable property for actions which require it.
In Struts 1.2.9 the <set-property> is used to set the cancellable property for an action....
<action path="/fooAction" input="/foo.jsp" validate="true"> <set-property property="cancellable" value="true"/> <forward name="success" path="/bar.jsp"/> </action>
From Struts 1.3.x a new cancellable attribute can be used....
<action path="/fooAction" input="/foo.jsp" validate="true" cancellable="true"> <forward name="success" path="/bar.jsp"/> </action>
In both Struts 1.2.9 and Struts 1.3.x an exception handler can be configured to handle the InvalidCancelException
<action path="/fooAction" input="/foo.jsp" validate="true" cancellable="true"> <forward name="success" path="/bar.jsp"/> <exception key="errors.cancel" type="org.apache.struts.action.InvalidCancelException" path="/foo.jsp"/> </action>
---------------------------------------end-----------------------------------------------------
刚好我用的是struts?.2.9?br />

ClassNotFoundException: org.hibernate.hql.ast.HqlToken 错误weblogic异常退出?
原因:
Hibernate3.0 采用新的ZANTLR的HQL/SQL查询译器，在Hibernate的配|文件中Qhibernate.query.factory_class属性用来选择查询译器?
Q?Q选择Hibernate3.0的查询翻译器Q?
hibernate.query.factory_class= org.hibernate.hql.ast.ASTQueryTranslatorFactory
Q?Q选择Hibernate2.1的查询翻译器
hibernate.query.factory_class= org.hibernate.hql.classic.ClassicQueryTranslatorFactory
Z使用3.0的批量更新和删除功能Q只能选择Q?Q否则不能解释批量更新的语句Q当使用的时候出C不支持条件输入中文的情况。选择Q?Q可以支持输入中文，但没法解释批量更新语句了
在hibernate3中需要用到antlrQ然而这个包在weblogic.jar中已l包含了antrlcdQ就会生一些类加蝲的错误，无法扑ֈ在war或者ear中的hibernate3.jar?
出现q个错误之后Qantlr会调用System.exit()Q这样weblogic׃中止服务?
解决Ҏ(gu):
1.是在hibernate.properties文g中增加属性：hibernate.query.factory_classQ属性的值是org.hibernate.hql.classic.ClassicQueryTranslatorFactoryQ这样就可以解决问题了?
但是部分功能会有问题Q譬?

2.antlr-2.7.5H3.jar到Weblogic的pre_Classpath :用WinRar或Winzip打开C:\bea\weblogic81\server\lib\weblogic.jar 删除里面的antlr目录, 然后再antlr-2.7.5H3.jar攑֜weblogic.jar的同一目录(?替换之后没做做过严格试,不知是否有后遗?
3. 1、拷贝Hibernate3里带的包antlr-2.7.5H3.jar?WL_HOME%\server\lib?
2、修? mydomain% \ startWebLogic.cmd Q?
在set CLASSPATH之前加上下面一句：
set PRE_CLASSPATH=%WL_HOME%\server\lib\antlr-2.7.5H3.jar;
在set CLASSPATH之后加上下面一句：

}
return criteria;
}
另外Q没有用OpenSessionInViewFilterQstruts与spring的整合：DelegatingRequestProcessor、action path与bean name同名?/font>
页不过10ơ，服务器就没响应了Q最后出C面的错误的了?/font>
刚用weblogicQ也刚用ssh套餐。郁闗?br />
前天解决了?br />
问题解决Q问题的原因是数据库q接耗尽Q我用HiberanteDaoSupport的getSession()Ҏ(gu)取得Session后没有释放Session?/p>
出问题的代码处（U色部分Q：
public Criteria createCriteria(Class entityClass, List criterions) {
Criteria criteria = getSession().createCriteria(entityClass);
if(criterions != null) {
for(int i=0; i
criteria.add((Criterion) criterions.get(i));
}
}
return criteria;
}
Criteria criteria = getSession().createCriteria(entityClass);
if(criterions != null) {
for(int i=0; i
criteria.add((Criterion) criterions.get(i));
}
}
return criteria;
}
用完Session释放后就没事了，调用HiberanteDaoSupport?font face="Arial">releaseSession(session);Ҏ(gu)后即可解冟?/font>
现在正确的代码：
public Page listByPage(Class entityClass, int pageNo, int pageSize, List criterions, List orders) {
Session session = getSession();
//创徏criteria
Criteria criteria = session.createCriteria(entityClass);
//为criteriadcriterions
createCriteria(entityClass, criteria, criterions);
CriteriaImpl impl = (CriteriaImpl) criteria;
// 先把Projection和OrderBy条g取出?清空两者来执行Count操作
Projection projection = impl.getProjection();
//获取总记录数
int totalCount = ((Integer) criteria.setProjection(Projections.rowCount()).uniqueResult()).intValue();
if(totalCount < 1) {
return new Page();
}
//加排?nbsp;
if(orders != null) {
for(int i=0; i
criteria.addOrder((Order) orders.get(i));
}
}
//原来的投?nbsp;
criteria.setProjection(projection);
int startIndex = Page.getStartOfPage(pageNo, pageSize);
//取得l果
List list = criteria.setFirstResult(startIndex).setMaxResults(pageSize).list();
//释放hiberante资源,一定要释放,要不然就数据库连接耗尽.
releaseSession(session);
return new Page(startIndex, totalCount, pageSize, list);
}
public Criteria createCriteria(Class entityClass, Criteria criteria, List criterions) {
if(criterions != null) {
for(int i=0; i
criteria.add((Criterion) criterions.get(i));
}
}
return criteria;
}
Session session = getSession();
//创徏criteria
Criteria criteria = session.createCriteria(entityClass);
//为criteriadcriterions
createCriteria(entityClass, criteria, criterions);
CriteriaImpl impl = (CriteriaImpl) criteria;
// 先把Projection和OrderBy条g取出?清空两者来执行Count操作
Projection projection = impl.getProjection();
//获取总记录数
int totalCount = ((Integer) criteria.setProjection(Projections.rowCount()).uniqueResult()).intValue();
if(totalCount < 1) {
return new Page();
}
//加排?nbsp;
if(orders != null) {
for(int i=0; i
criteria.addOrder((Order) orders.get(i));
}
}
//原来的投?nbsp;
criteria.setProjection(projection);
int startIndex = Page.getStartOfPage(pageNo, pageSize);
//取得l果
List list = criteria.setFirstResult(startIndex).setMaxResults(pageSize).list();
//释放hiberante资源,一定要释放,要不然就数据库连接耗尽.
releaseSession(session);
return new Page(startIndex, totalCount, pageSize, list);
}
public Criteria createCriteria(Class entityClass, Criteria criteria, List criterions) {
if(criterions != null) {
for(int i=0; i
criteria.add((Criterion) criterions.get(i));
}
}
return criteria;

2、利用Configuration Wizard配置Domain和serverQ按照缺省即?br />
如：
W二部后Q我Zl果Q有了D:\bea\user_projects\domains\mydomain目录其中mydomain是向g自己写的。然后把web应用E序攑ֈD:\bea\user_projects\domains\mydomain\applications目录中，applications相当于Tomcat中的webapps目录?br />
WEB-INF目录下可以不用weblogic.xml文gQ文件内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE weblogic-web-app PUBLIC "-//BEA Systems, Inc.//DTD Web Application 8.1//EN" "http://www.bea.com/servers/wls810/dtd/weblogic810-web-jar.dtd">
<weblogic-web-app>
<context-root>/WebModule1</context-root>
</weblogic-web-app>
<!DOCTYPE weblogic-web-app PUBLIC "-//BEA Systems, Inc.//DTD Web Application 8.1//EN" "http://www.bea.com/servers/wls810/dtd/weblogic810-web-jar.dtd">
<weblogic-web-app>
<context-root>/WebModule1</context-root>
</weblogic-web-app>
如果?lt;context-root>/WebModule1</context-root>QWebModule1才是web应用的根地址Q访问地址成了这Phttp://localhost:7001/WebModule1/index.jsp
如果没有<context-root>/WebModule1</context-root>或没有weblogic.xml文gQ访问地址为：http://localhost:7001/blank/index.jsp
其中blank是applications下的Web应用E序的根目录?

1.用tomcat里面的例?在webapps\servlets-examples\WEB-INF\classes\里把filters目录攑ֈ你的classer\?其实只要SetCharacterEncodingFilter可以了,在web.xml里加
<filter>
<filter-name>Set Character Encoding</filter-name>
<filter-class>filters.SetCharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>Set Character Encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter-name>Set Character Encoding</filter-name>
<filter-class>filters.SetCharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>Set Character Encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
2.如果用springQ用spring提供的过虑器Q同样在web.xml里加
<filter>
<filter-name>Set Character Encoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>Set Character Encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter-name>Set Character Encoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>Set Character Encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

因ؓms word和excel的文档都支持html文本格式Q因此可以先用word或excel做好模版Q另存ؓweb，然后该htmlҎ(gu)jspQ将数据部分动态填入即可，不用很辛苦的调整格式 ?/p>
word面只要在jsp头设|如下指令：

poi加中文有问题

cell.setEncoding(HSSFCell.ENCODING_UTF_16);

用Jexcelapi试下发现不会出现中文问题,是因为它是韩国h写的?以多字节字符为根?br />
